摘要:
Devices and methods of paging user equipment (UE) are generally described. An evolved Node-B (eNB) may transmit legacy and extended coverage paging messages having different Paging Radio Network Temporary Identifiers (P-RNTIs) to UEs. Each extended coverage paging message may contain the same information, which coverage constrained UEs may combine to achieve a predetermined link budget and subsequently decode. The coverage constrained UEs may ignore legacy paging messages prior to decoding the legacy paging messages. The extended coverage paging messages may be transmitted in non-legacy paging occasions that may span multiple paging cycles. Each paging cycle may contain 0, 1 or multiple extended coverage paging occasions. The UE may be provided the physical resource blocks (PRBs) used for the extended coverage paging message through a system information message. The PRBs may be assigned as a fixed or semi-statically assigned set of PRBs or a dynamically assigned set of PRBs.

Embodiments of an enhanced Node B (eNB) and method for RRC connection establishment for small-data transfers in a 3GPP LTE network are generally described herein. The eNB may receive a small-data RRC connection request message from user equipment (UE) that may include an establishment clause value indicating small-data traffic either with or without mobility. The eNB may send an initial UE setup request message to inform the mobility management entity (MME) that a small-data RRC connection is being established. The eNB may receive an acceptance message from the MME for the small-data RRC connection which may include a reduction of an RRC inactivity timer for fast connection release. The eNB may send an RRC connection reconfiguration message to the UE in response to receipt of the acceptance to establish the small-data RRC connection, the RRC connection reconfiguration message including a measurement information element (IE) when mobility is to be supported.

In typical UEs, scanning for WiFi access points (APs) can consume a significant amount of power. This scanning occurs when the UE is connected through the cellular network, but does not occur when the UE is connected to a WiFi network. As a result, offloading a UE from a cellular network to a WiFi network can allow the UE to conserve power. An issue with existing cellular networks is that the UE cannot inform a cellular network that the UE is running low on power, and therefore cannot direct the cellular network to offload the UE for power conservation reasons. A technique discussed herein allows the UE to indicate its power saving needs to the cellular network. In response, the cellular network can lower (or raise) a particular threshold, so that the UE now exceeds (or no longer exceeds) the threshold, and initiates offloading.

An embodiment of methods and user equipment are disclosed. Once such method includes a user equipment transmitting preferences for Flow-to-RAT mapping to a base station of a network. The user equipment may receive a Flow-to-RAT mapping from the base station that specifies a particular RAT to be associated with a particular Flow.

Embodiments of an enhanced Node B (eNB) and method to provide system information (SI) updates to user equipment (UE) in sleep or idle mode with an extending paging cycle are generally described herein. In some embodiments, a paging message configured to include an optional field to indicate whether there has been a system information (SI) update since a last paging occasion for a UE in sleep or idle mode with an extending paging cycle. System information updates are transmitted by the eNB during a system information modification period that is shorter than a period the extending paging cycle. The optional field may indicate whether or not the UE is to acquire the latest SI update during the current paging occasion.

Embodiments of wireless communication devices and method for discontinuous reception (DRX) mode in wireless communication are generally described herein. Some of these embodiments describe a wireless communication device having a module to cause the wireless communication device to enter the DRX mode in an operational state of the wireless communication device. The DRX mode may include a DRX cycle having a DRX cycle length. The DRX cycle length may have a value greater than at least four values of DRX cycle lengths supported by an enhanced node-B.

Embodiments for signaling quality of service (QoS) requirements and user equipment (UE) power preference in LTE-A networks are generally described herein. In some embodiments, a power preference indication (PPI) is received at an eNB from a UE to set a power saving preference for the UE. A communication session is established using radio resource control (RRC) messages between the UE and the eNB to identify a preference for QoS configuration for handling traffic provided to the UE by the eNB. The QoS for traffic provided by the eNB to the UE is managed by the eNB based on the identified preference for QoS configuration for handling traffic provided to the UE.

Systems and techniques for traffic splitting based on latency between cells are herein described. At an eNodeB, a transmission path latency for a portion of a transmission path between the eNodeB and a user equipment (UE) may be measured via a secondary eNodeB when the UE is dually connected to both the eNodeB and the secondary eNodeB. The transmission path latency may be compared to a threshold. A layer in a transmission stack to split traffic to the UE may be determined based on the comparison of the transmission path latency to the threshold, the traffic being split between the eNodeB and the secondary eNodeB.

Embodiments of wireless communication devices and method for discontinuous reception (DRX) mode in wireless communication are generally described herein. Some of these embodiments describe a wireless communication device having processing circuitry arranged to determine to use an extended paging discontinuous reception (DRX) value to increase a paging cycle length above a value and select a first periodicity, based on the extended paging DRX value, at which the UE is to perform evaluation of a parameter of a network in which the UE is opera. The wireless communication device may have physical layer circuitry arranged to transmit a message to the network, indicating that the UE desires to perform evaluation of the parameter at the first periodicity. Other methods and apparatuses are also described.
